Abstract

PCT No. PCT/CH84/00082 Sec. 371 Date Oct. 22, 1985 Sec. 102(e) Date Oct. 22, 1985 PCT Filed May 23, 1984 PCT Pub. No. WO85/03732 PCT Pub. Date Aug. 29, 1985.Electrical conductors wound into coils (4, 5) are disposed in a housing (1). The axes of the coils (4, 5) run perpendicular to the base of the housing. Each coil (4, 5) is connected with a capacitor (2, 3) so that oscillatory circuits are formed. The longitudinal axes (10, 11) of the capacitors (2, 3) cross the coil axes at right angles and consequently run parallel to the base of the housing. In one (4) of the coils (4, 5) a permanent magnet (6) is inserted. Each coil has its own number of windings, its own outer diameter (15, 16), and advantageously its own inside diameter (18, 19). The oscillatory circuits are closed or opened by a switch (12). The oscillatory circuits are excited by the interfering fields present and generate in their turn a counter field. The process conforms essentially to the Lenz law of physics, according to which the reaction produced in the apparatus counteracts, and in the ideal case eliminates, the stimulating field action which produces it. As a result, the water in the capillary of the walling can no longer rise and the walling dries out in natural ways.

Description

Die Erfindung bezieht sich auf ein Gerät zur Entfeuchtung von Mauerwerk bei im Mauerwerk aufsteigender Feuchtigkeit, welches Gerät Kondensatoren und zu Spulen gewundene elektrische Leiter aufweist, wobei die beiden Pole eines jeweiligen Kondensators mit je einem Ende eines jeweiligen zur Spule gewundenen elektrischen Leiters verbunden sind.The invention relates to a device for dehumidifying masonry when moisture rises in the masonry, which device has capacitors and electrical conductors wound into coils, the two poles of a respective capacitor being connected to one end of a respective electrical conductor wound into a coil.

Im Mauerwerk von Gebäuden werden durch aufsteigende Feuchtigkeit, hervorgerufen z. B. durch Grundwasser, Stauwasser, Sickerwasser oder unterirdisch fliessende Gewässer beträchtliche Schäden verursacht.In the masonry of buildings are caused by rising damp, z. B. caused considerable damage by groundwater, backwater, leachate or underground water.

Da alle Baustoffe mehr oder weniger porös sind, saugen sie auf Grund ihrer Kapillarität das Wasser an, so dass dieses innerhalb der Mauern hochsteigen kann.Since all building materials are more or less porous, they suck in the water due to their capillarity, so that it can rise inside the walls.

Der offene Kreislauf von Wasser in einer nassen Mauer, bedingt durch den osmotischen Druck, wird von unten nach oben und hier durch Verdunsten nach aussen geführt. Durch diesen Wassertransport wird ein elektrisches Feld in Richtung der steigenden Feuchtigkeit aufgebaut, dieses Feld wirkt als Pumpe.The open cycle of water in a wet wall, caused by the osmotic pressure, is led from the bottom up and here by evaporation to the outside. This water transport creates an electric field in the direction of the rising humidity, this field acts as a pump.

Feuchtes Mauerwerk führt nicht nur zu bautechnischen Schäden wie teilweisen Zerfall, kristallinen Ausblühungen, Krustenbildung etc., sondern kann auch zu Erkrankungen von Menschen führen, die sich in Bauten mit feuchtem Mauerwerk aufhalten, z. B. Rheuma, Asthma, Infektionskrankheiten, etc., und vor allem entsteht auch ein sehr unwohnliches Raumklima in solchen Bauten.Moist masonry not only leads to structural damage such as partial decay, crystalline efflorescence, crust formation, etc., but can also lead to diseases of people who are in buildings with damp masonry, e.g. B. rheumatism, asthma, infectious diseases, etc., and above all, a very unusual indoor climate arises in such buildings.

Es ist bekannt, in Mauern aufsteigende Feuchtigkeit durch einlegen von Isolierlagen zu bekämpfen. Weiter sind verschiedene sogenannte Elektroosmoseverfahren bekannt, welche meistens beträchtliche bauliche Massnahmen bedingen, nicht an jeder Stelle und ohne Schwierigkeiten durchführbar sind (Bohren in Hauswänden), und in vielen Fällen in keinem Verhältnis zum erzielten Erfolg stehen.It is known to combat rising damp in walls by inserting insulating layers. Furthermore, various so-called electro-osmosis processes are known, which mostly require considerable structural measures, cannot be carried out at any point and without difficulty (drilling in house walls), and in many cases are disproportionate to the success achieved.

Bewegen sich die Oberflächen zweier Stoffe aneinander vorbei (Reibung), laden sich die beiden Stoffe an ihren Grenzschichten entgegengesetzt elektrisch auf. Hat dabei der eine Stoff eine grössere elektrische Leitfähigkeit als der andere Stoff, so lädt sich der erste positiv, der zweite negativ elektrisch auf.If the surfaces of two substances move past each other (friction), the two substances charge against each other electrically at their boundary layers. If one substance has a greater electrical conductivity than the other substance, the first is charged positively, the second negatively electrically.

Bewegt sich Wasser in kapillarem Mauerwerk, so ist seine elektrische Ladung jener des Mauerwerks entgegengesetzt. Es entsteht zwischen den beiden Grenzschichten eine elektrische Potentialdifferenz, das ZETA-POTENTIAL. Das Wasser wird dabei durch die entgegengesetzten elektrischen Ladungen in den Kapillaren hochgezogen und benetzt somit weite Bereiche des Mauerwerkes. Es sind jedoch noch weitere Faktoren mitbestimmend, unter anderem die im Wasser gelösten Salze, die Luftionisation, etc. In der Fachwelt wird angenommen, dass alle diese Faktoren von den Wasserverhältnissen im Erdboden beeinflusst werden, weil unterirdisch strömendes Wasser bekanntlich elektrische und magnetische Felder zur Folge hat, die in ihrer Stärke stark schwanken, wodurch die elektrische Leitfähigkeit des Wassers verändert wird. Als weitere Ursachen wirken vor allem diese natürlichen Reizfelder und vermehrt auch durch technische Anlagen (z. B. erdverlegte Hochspannungsleitungen etc.) entstehende, sogenannte zivilisatorische Reizfelder.If water moves in capillary masonry, its electrical charge is opposite to that of masonry. There is an electrical potential difference between the two boundary layers, the ZETA-POTENTIAL. The water is drawn up by the opposite electrical charges in the capillaries and thus wets large areas of the masonry. However, other factors also play a role, including the salts dissolved in the water, air ionization, etc. Experts believe that all of these factors are influenced by the water conditions in the ground, because water flowing underground is known to result in electrical and magnetic fields that vary greatly in strength, which changes the electrical conductivity of the water. These natural stimulus fields act as further causes and, increasingly, so-called civilizational stimulus fields arising from technical systems (e.g. buried high-voltage lines, etc.).

Diese Reizfelder verlaufen je nach geophysikalischen Verhältnissen in weit ausgedehnten Bereichen, bzw. Reizzonen. Verläuft nun eine solche Zone durch ein Gebäude, wird das Reizfeld stark inhomogen. In elektrisch isolierendem Mauerwerk ist die Feldstärke grösser als in dem von ihm umschlossenen Innenraum, welche Tatsache auf Grund der stark dielektrischen Eigenschaften von Wasser zur Transport der Wassermoleküle führt, entweder im Mauerwerk selbst kapillar aufsteigend oder durch Diffusion aus der Luft zum Mauerwerk. Dieses ist die Ursache der Feuchtigkeitsbildung.Depending on the geophysical conditions, these stimulus fields run in extensive areas or stimulation zones. If such a zone now runs through a building, the stimulus field becomes very inhomogeneous. In electrically insulating masonry, the field strength is greater than in the interior enclosed by it, which fact leads to the transport of water molecules due to the strongly dielectric properties of water, either ascending in the masonry itself or by diffusion from the air to the masonry. This is the cause of moisture formation.

Was die physikalische Natur der Reizfelder betrifft, hegt die Fachwelt nach neuesten Erkenntnissen die Vermutung, dass eine Reizzone eine Region darstellt, in der starke Aktivität von stillen atmosphärischen Entladungen herrscht. Diese Entladungen haben den Charakter von Ladungsfluktuationen beziehungsweise dipolartigen Anregungszuständen, deren Beschreibung in den Bereich der Quantenphysik fällt. Sie scheinen dem Mechanismus der Pause bei atmosphärischen Blitzentladungen verwandt zu sein.As far as the physical nature of the stimulus fields is concerned, experts believe that a stimulus zone is a region where there is strong activity from silent atmospheric discharges. These discharges have the character of charge fluctuations or dipole-like excitation states, the description of which falls in the field of quantum physics. They seem to be related to the pause mechanism in atmospheric lightning discharges.

Es ist ein Entfeuchtungsgerät gemäss dem Oberbegriff des Patentanspruches 1 bekannt (US-A-4 418 481), bei dem zwei Spulen vorhanden sind, die mit jeweils einem Kondensator verbunden sind, wobei die Längsachsen der Kondensatoren die Achsen der mit ihnen verbundenen Spulen kreuzen. Dabei laufen die Achsen der Spulen senkrecht zueinander. Mit diesem Gerät lässt sich nur das elektrische Erdfeld beeinflussen. Es hat sich in der Praxis gezeigt, dass das Gerät das Aufsteigen von Feuchtigkeit in Mauerwerk verhindern kann. Eine genaue, abschliessende technische Erklärung für diesen Effekt kann noch nicht gemacht werden, es wird jedoch vermutet, dass dieses Gerät auf Eigenheiten, bzw. Veränderungen des elektrischen bzw. magnetischen Erdfeldes anspricht und seinerseits einen beeinflussenden Faktor bildet, welcher der im Mauerwerk aufsteigenden Bodenfeuchtigkeit entgegenwirkt. Dieses bekannte Gerät benötigt keine Energiezufuhr ausser jener des Erdfeldes.A dehumidifier according to the preamble of claim 1 is known (US-A-4 418 481), in which there are two coils each connected to a capacitor, the longitudinal axes of the capacitors crossing the axes of the coils connected to them. The axes of the coils run perpendicular to each other. This device can only be used to influence the earth's electrical field. It has been shown in practice that the device can prevent moisture from building up in masonry. A precise, concluding technical explanation for this effect cannot yet be made, but it is assumed that this device responds to peculiarities or changes in the electrical or magnetic earth field and in turn forms an influencing factor that counteracts the rising moisture in the masonry . This known device requires no energy supply other than that of the earth's field.

Die Praxis hat nun aber gezeigt, dass es immer wieder Orte gibt, an denen das bekannte Gerät nur teilweise funktioniert. Insbesondere an Orten, an denen nur relativ schwache Erdfeldanomalien oder vorwiegend Anomalien des magnetischen Erdfeldes vorhanden waren, brachte dieses Gerät meist nicht den gewünschten Erfolg.Practice has now shown that there are always places where the known device only works partially. In particular, in places where there were only relatively weak earth field anomalies or predominantly anomalies of the magnetic earth field, this device usually did not achieve the desired success.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, ein Gerät zur Entfeuchtung von Mauerwerk zu schaffen, welches in seiner Wirksamkeit erheblich gesteigert ist, und vor allem auch an den Orten mit Erfolg eingesetzt werden kann, an denen die bekannten Geräte nicht oder mindestens nicht zur vollen Zufriedenheit funktionierten.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a device for dehumidifying masonry, which is significantly increased in its effectiveness, and above all can be used successfully in places where the known devices did not work or at least did not work to full satisfaction.

Die durch die Erfindung erreichten Vorteile sind om wesentlichen darin zu sehen, dass das Gerät auch an den Orten mit relativ schwachen örtlichen Erdfeldanomalien und vor allem völlig unabhängig von der Konstellation der vorhandenen Störfelder, d.h. diese können magnetischer, elektromagnetischer oder elektrischer Natur oder als Wechselwirkung dieser Kräfte bebildet sein, mit vollem Erfolg eingesetzt werden kann.The advantages achieved by the invention are essentially to be seen in the fact that the device also in locations with relatively weak local earth field anomalies and above all completely independent of the constellation of the existing interference fields, i.e. these can be magnetic, electromagnetic or electrical in nature or can be formed as an interaction of these forces, can be used with great success.

Im folgenden wird die Erfindung anhand mehrerer Ausführungswege darstellender Zeichnungen erläutert. Es zeigt:

  • Fig. 1 einen Schnitt entlang der Linie I-I der Fig. 2, wobei ein erster Ausführungsweg gezeichnet ist;
  • Fig. 2 einen Schnitt entlang der Linie 11-11 der Fig. 1 der Darstellung eines ersten Ausführungsweges;
  • Fig. 3 eine Darstellung gleich der Fig. 2 eines zweiten Ausführungsweges mit drei Spulen; und
  • Fig. 4 eine Darstellung gleich der Fig. 1 eines dritten Ausführungsweges mit gedruckten Schaltungen für die Spulen.
In the following, the invention will be explained with reference to drawings showing several possible embodiments. It shows:
  • 1 shows a section along the line II of Figure 2, wherein a first embodiment is drawn.
  • FIG. 2 shows a section along the line 11-11 of FIG. 1 illustrating a first embodiment;
  • Fig. 3 is an illustration like Figure 2 of a second embodiment with three coils. and
  • Fig. 4 is an illustration like Fig. 1 of a third embodiment with printed circuits for the coils.

Das Gerät weist ein Gehäuse aus einem nicht elektrisch leitenden Stoff auf, welches Gehäuse in allen Figuren mit der Bezugsziffer 1 bezeichnet ist. Im Gehäuse 1 sind nach dem in der Figuren 1 und 2 gezeichneten Ausführungsweg ein erster Kondensator 2 und ein zweiter Kondensator 3 angeordnet. Weiter sind ein erster, zu einer ersten Spule 4 gewundener Leiter und ein zweiter, zu einer zweiten Spule 5 gewundener Leiter vorhanden. Der erste Kondensator 2 ist einerends mit dem einen Ende und andererends mit dem anderen Ende der ersten Spule 4 verbunden, und der zweite Kondensator 5 ist einerends mit dem einen Ende und andererends mit dem anderen Ende der zweiten Spule 5 verbunden. Damit ergeben sich zwei Schwingkreise begründende Schaltungen. In der Mitte der ersten Spule 4 ist neben dem ersten Kondensator 2 ein Permanentmagnet 6 angeordnet. Die Mittelachsen 7, 8 der Spulen 4, 5 verlaufen senkrecht zum die Auflagefläche des Gerätes bildenden Boden 9 des Gehäuses 1. Die Längsachsen 110, 11 der Kondensatoren 2, 3 kreuzen die Mittelachsen 7, 8 der Spulen 4, 5 rechtwinklig und verlaufen somit parallel zum Boden 9 des Gehäuses.The device has a housing made of a non-electrically conductive material, which housing is designated by the reference number 1 in all figures. A first capacitor 2 and a second capacitor 3 are arranged in the housing 1 according to the embodiment shown in FIGS. 1 and 2. There are also a first conductor wound to a first coil 4 and a second conductor wound to a second coil 5. The first capacitor 2 is connected at one end to one end and at the other end to the other end of the first coil 4, and the second capacitor 5 is connected at one end to the one end and at the other end to the other end of the second coil 5. This results in two circuits that form the basis of oscillating circuits. A permanent magnet 6 is arranged in the middle of the first coil 4 next to the first capacitor 2. The central axes 7, 8 of the coils 4, 5 run perpendicular to the base 9 of the housing 1 forming the bearing surface of the device. The longitudinal axes 110, 11 of the capacitors 2, 3 cross the central axes 7, 8 of the coils 4, 5 at right angles and thus run parallel to the bottom 9 of the housing.

Um das Gerät in Betrieb zu setzen, bzw. ausser Betrieb nehmen zu können, ist jedem Schwingkreis ein Schalter 12 zugeordnet. Es kann hier ein mehrpoliger Schalter vorhanden sein, so dass mittels Betätigung, z. B. eines Druckknopfes beide Schwingkreise geschlossen, bzw. unterbrochen werden können.A switch 12 is assigned to each resonant circuit in order to put the device into operation or to take it out of operation. There may be a multi-pole switch here, so that by means of actuation, for. B. a push button both resonant circuits can be closed or interrupted.

Das Gerät nach der Fig. 3 unterscheidet sich von der in den Fig. 1 und 2 gezeigten Ausführung, indem eine dritte Spule 13 vorhanden ist. Diese dritte Spule 13 ist mit dem ersten Kondensator 2 verbunden, ist also parallel zur ersten Spule 4 geschaltet. Die Achse der dritten Spule 13 fällt mit der Achse der ersten Spule 4 zusammen.3 differs from the embodiment shown in FIGS. 1 and 2 in that a third coil 13 is provided. This third coil 13 is connected to the first capacitor 2, and is therefore connected in parallel to the first coil 4. The axis of the third coil 13 coincides with the axis of the first coil 4.

Die Spulen 2, 3 bzw. 13 der in den Figuren 1-3 gezeichneten Ausführungen sind durch gewundene Leiter gebildet. Ein solcher Leiter kann ein isolierter Draht, z. B. eine Kupferlitze oder ein lackierter Kupferdraht sein. Die Spulen können auch zum Teil durch eine gedruckte Schaltung gebildet sein, wobei eine Ausführung in der Fig. 4 gezeichnet ist. Es können alle Spulen 2, und auch 13, falls eine Ausführung mit drei Spulen vorhanden ist, oder auch nur eine Spule als ebene gedruckte Schaltung gebildet sein.The coils 2, 3 and 13 of the designs shown in Figures 1-3 are formed by winding conductors. Such a conductor can be an insulated wire, e.g. B. a copper braid or a painted copper wire. The coils can also be partially formed by a printed circuit, an embodiment being drawn in FIG. 4. All coils 2, and also 13, if a version with three coils is present, or only one coil can be formed as a flat printed circuit.

In der Ausführung, die in der Fig. 4 gezeichnet ist, sind die erste Spule 4 und die zweite Spule 5 als gedruckte Schaltung gebildet. Wieder ist in der ersten Spule 4 ein Permanentmagnet angeordnet. Die Längsachsen 10, 11 der Kondensatoren 2, 3 kreuzen die Mittelachsen der Spulen 4, 5 auch hier rechtwinklig. Jedoch sind in der Ausführung nach Fig. 4 die Kondensatoren 2, 3 als auf der Spulen 4, 5 aufgelegt zu betrachten, und nicht von der Spulen 4, 5 umgeben, wie dies der Fall bei den Ausführungen gemäss der Fig. 1-3 ist.In the embodiment which is drawn in FIG. 4, the first coil 4 and the second coil 5 are formed as a printed circuit. Again, a permanent magnet is arranged in the first coil 4. The longitudinal axes 10, 11 of the capacitors 2, 3 also cross the central axes of the coils 4, 5 at right angles here. However, in the embodiment according to FIG. 4, the capacitors 2, 3 are to be regarded as placed on the coils 4, 5 and are not surrounded by the coils 4, 5, as is the case with the embodiments according to FIGS. 1-3 .

Das Gehäuse 1 aller Ausführungen besteht aus elektrisch nicht leitendem Stoff, insbesondere aus Kunststoff, um Abschirmungen des auf das Gerät einwirkenden Erdfeldes, bzw. der Störfelder zu vermeiden. Ein Deckel 14 (siehe Fig. 3) schliesst das Gehäuse 1 ab, wobei dieser Deckel 14 zur besseren Energieaufnahme und Energieabgabe mit Löchern oder Schlitzen versehen sein kann.The housing 1 of all versions consists of electrically non-conductive material, in particular plastic, in order to avoid shielding the earth's field acting on the device or the interference fields. A cover 14 (see FIG. 3) closes off the housing 1, and this cover 14 can be provided with holes or slots for better energy absorption and energy dissipation.

Der Ausdruck "Spule" ist im Sinne einer elektrischen Induktivität zu verstehen. Die jeweiligen Kondensatoren 2, 3 bilden mit den dazugehörigen Spulen 4, 5, 13 einen praktisch dämpfungslosen elektrischen Parallelschwingkreis, der im wesentlichen dem Lenz'schen Gesetz der Physik entspricht, wonach die im Gerät ausgelöste Reaktion der sie erzeugenden Reizfeldreaktion entgegenwirkt und im Idealfall eliminiert. Die Schwingfrequenz der jeweiligen Schwingkreise liegt im allgemeinen im Bereich von 10 - 44 kHz bzw. 30 - 150 MHz. Die Grösse der Kondensatoren liegt im allgemeinen zwischen 0,1 und 2,5 uF. Die Spulen weisen jeweils mehrere Windungen auf, zumindest drei Windungen.The term "coil" is to be understood in the sense of an electrical inductance. The respective capacitors 2, 3, together with the associated coils 4, 5, 13, form a practically damping-free electrical parallel resonant circuit, which essentially corresponds to Lenz's law of physics, according to which the reaction triggered in the device counteracts and, ideally, eliminates the stimulus field reaction that generates it. The oscillation frequency of the respective oscillation circuits is generally in the range of 10 - 44 kHz or 30 - 150 MHz. The capacitors are generally between 0.1 and 2.5 uF in size. The coils each have several turns, at least three turns.

Die Aussendurchmesser 15,16,17 der Spulen 4, 5, 13 (Siehe Fig. 1 und 3) sind jeweils verschieden gross. Bei weiteren Ausführungen sind zudem die Innendurchmesser 18, 19, 20 ebenfalls jeweils verschieden gross.The outer diameters 15, 16, 17 of the coils 4, 5, 13 (see FIGS. 1 and 3) are each of different sizes. In other versions, the inner diameters 18, 19, 20 are also each of different sizes.

Das Mass (Aussendurchmesser - Innendurchmesser = MD) des mittleren Durchmessers MD, siehe die rechts liegende Spule 5 der Fig. 1, die kleinste Spule, beträgt mindestens 5 cm.The dimension (outer diameter - inner diameter = MD) of the mean diameter MD, see the coil 5 on the right in FIG. 1, the smallest coil at least 5 cm.

Um zu vermeiden, dass z. B. bei Erschütterungen des Gerätes sich einzelne Bauteile im Gehäuse 1 verschieben können, ist das Gehäuse 1 vorteilhaft mit Kunstharz gefüllt. Überdies können auch das Gehäuse 1 und der Deckel 14 selbst aus Kunstharz hergestellt sein. Die Gehäusefüllung bildet eine Verstärkung der Wände des Gehäuses, wobei die einzelnen Bauteile im Kunstharz eingegossen sind.To avoid z. B. individual components in the housing 1 can move when the device is shaken, the housing 1 is advantageously filled with synthetic resin. In addition, the housing 1 and the lid 14 itself can also be made of synthetic resin. The housing filling forms a reinforcement of the walls of the housing, the individual components being cast in synthetic resin.

Das Gerät ist auch dann funktionstüchtig, wenn der Kondensator nicht mehr als den mittleren Durchmesser MD der jeweiligen Spule vom Zentrum derselben entfernt ist.The device is also functional when the capacitor is no more than the average diameter MD of the respective coil from the center thereof.

Zum Einsatz des Entfeuchtungsgerätes wird zuerst bei der Einsatzstelle mittels eines elektromagnetische Wellen anzeigenden Gerätes das Störfeld geortet, bzw. seine Feldstärke ermittelt. Das Gerät wird darauf nicht unmittelbar auf die Reizstreifen eines Störfeldes oder der Stelle der höchsten Feldstärke, sondern neben einer solchen Stelle aufgestellt und durch Schliessen der Schaltkreise durch Betätigung der Schalter, bzw. des Schalters 12 in Betrieb gesetzt. Die Reichweite eines Gerätes kann bis zu mehreren Hundert Metern betragen.To use the dehumidifier, the interference field is first located at the place of use by means of an electromagnetic wave-indicating device, or its field strength is determined. The device is then not placed directly on the stimulus strips of an interference field or the location of the highest field strength, but next to such a location and put into operation by closing the circuits by actuating the switches or the switch 12. The range of a device can be up to several hundred meters.

Die zentrische Anordnung der Kondensatoren relativ zu den ihnen zugeordneten Spulen macht das Gerät unabhängiger von seinem Aufstellungsort und seiner Aufstellungsrichtung.The central arrangement of the capacitors relative to the coils assigned to them makes the device more independent of its location and direction of installation.

Durch die Energie der vorhandenen Störfelder werden die im Gerät angeordneten Schwingkreise erregt und erzeugen ihrerseits ein Gegenfeld. Durch die Interferenz der nun vorhandenen Felder werden diese jetzt zumindest im Bereiche der zurzeit bekannten Nachweisbarkeit so stark verringert, dass als Effekt eine messbare Verringerung der elektrokinetisch bedingten Potentialdifferenz sowie der Luftkonenkonzentration eintritt, was zur Folge hat, dass das Wasser im Mauerwerk nicht mehr aufsteigen kann und das Mauerwerk auf natürlichem Wege austrocknen kann.The oscillating circuits arranged in the device are excited by the energy of the existing interference fields and in turn generate an opposing field. Due to the interference of the fields now present, these are now reduced so much, at least within the range of the currently known detectability, that the effect is a measurable reduction in the electrokinetic potential difference and the air concentration, which means that the water in the masonry can no longer rise and can dry out the masonry naturally.
